MK672 - Ludlamite with Siderite $ 4500 SOLD Blackbird Mine, Lemhi Co., Idaho, USA small cabinet - 7.5 x 4.2 x 2.2 cm ![]() ![]() ![]() Gemmy, sharp green crystals of Ludlamite over Siderite from the famous Blackbird Mine in Idaho. The Ludlamite form abundant sharp and bright green crystals liberally sprinkled across a surface of botryoidal Siderite. This is old, classic USA material from a defunct cobalt mine that produced some of the world's best Ludlamite. The specimen is from the collection of Don Boyston of Los Angeles, California. I purchased this in 2005 when his collection was sold. Don had a number of Blackbird Ludlamites in the collection - this was my favorite and I've held onto it all this time.

MK675 - Rhodochrosite $ 2800 SOLD N'Chwanning Mine, Kuruman, South Africa miniature - 3.7 x 3 x 3 cm ![]() ![]() ![]() ![]() Cluster of cherry-red, transparent Rhodochrosite crystals. The color and transparency are superb. There are some smaller cleaved crystals on the edges, but the main crystal is perfect and transparent all the way to the base. In fact looking at this there is quite a bit of cutting rough value.

There are some bits of matrix attached to the crystals on back, but this is essentially a floater cluster of nothing but intergrown Azurite crystals. Highly showy example from this prolific Azurite locality that is no longer producing.

This is likely from the Karo Mine where the best Apatite were found years ago. This is an excellent crystal and the pictures don't do it justice.
